C# Quartz的配置

1. 介绍

Quartz为后台工作者提供了得便利，我们下面介绍一下它的配置。本文配置主要针对服务程序的配置。

但是在做下面配置之前，要安装包

Install-Package Quartz

2. Quartz配置有两种方法，第一种是纯XML配置；第二种是抛弃XML文件配置，用纯代码配置。

2.1 Quartz下的纯XML配置

1）首先新建job配置XML文件quartz_jobs.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">

  <processing-directives>
    <overwrite-existing-data>true</overwrite-existing-data>
  </processing-directives>

  <schedule>

    <!--开始执行一个调度-->
    <job>
      <name>TestJob</name>
      <group>TestJobGroup</group>
      <description>TestJobDescription</description>
      <job-type>FeiDuWindowService.Job.TestJob, FeiDuWindowService</job-type>
      <durable>true</durable>
      <recover>false</recover>
    </job>

    <trigger>
      <cron>
        <name>TestJobTrigger</name>
        <group>TestJobTriggerGroup</group>
        <job-name>TestJob</job-name>
        <job-group>TestJobGroup</job-group>
        <cron-expression>*/5 * * * * ?</cron-expression>
      </cron>
    </trigger>
    <!--结束一个调度-->

  </schedule>
</job-scheduling-data>

说明： job标签下面的name与group随便怎么写。注意job-type标签要写类的具体包路径，与项目名称。

trigger下面的cron-expression标签说明每5秒钟运行一次。

2）新建job类，继承IJob

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using FeiDuWindowService.Helper;
using Quartz;

namespace FeiDuWindowService.Job
{
    public class TestJob:IJob
    {
        public void Execute(IJobExecutionContext context)
        {
            try
            {
                LogHelper.InfoLog.InfoFormat("--执行job-- " + DateTime.Now);
            }
            catch (Exception e)
            {

            }
        }
    }
}

3）项目启动时，配置加载xml文件

           //加载xml job的配置文件
             NameValueCollection properties = new NameValueCollection();
            properties["quartz.plugin.xml.type"] = "Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz";
            properties["quartz.plugin.xml.fileNames"] = "~/Job/quartz_jobs.xml";
            //开启job
            ISchedulerFactory sf = new StdSchedulerFactory(properties);
            IScheduler sched = sf.GetScheduler();
            if(!sched.IsStarted)
                sched.Start();

2.2 Quartz的纯代码

用纯代码很简单，什么都不用配置，直接上代码

            ISchedulerFactory factory = new StdSchedulerFactory();
            IScheduler scheduler = factory.GetScheduler();
            if (!scheduler.IsStarted)
            {
                IJobDetail testjob = JobBuilder.Create<TestJob>().WithIdentity("TestJob", "TestJobGroup").Build();
                //将任务与触发器关联起来放到调度器中
                ITrigger trigger = TriggerBuilder.Create().StartNow().WithIdentity("TestjobTrigger", "TestjobTriggerGroup").WithCronSchedule("*/5 * * * * ?").Build();
                scheduler.ScheduleJob(testjob, trigger);

                scheduler.Start();

                LogHelper.InfoLog.Info("--启动job OnStart--");
            }

3. job在App.config的配置

可以不加这个配置，但是为了易于管理，我们一般把下面的JOB配置加到App.config下面

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <configSections>
    <section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
    <sectionGroup name="common">
      <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging"/>
    </sectionGroup>
  </configSections>
  <common>
    <logging>
      <factoryAdapter type="Common.Logging.Simple.ConsoleOutLoggerFactoryAdapter, Common.Logging">
        <arg key="showLogName" value="true"/>
        <arg key="showDataTime" value="true"/>
        <arg key="level" value="INFO"/>
        <arg key="dateTimeFormat" value="HH:mm:ss:fff"/>
      </factoryAdapter>
    </logging>
  </common>

    <add key="quartz.dbprovider.customProvider.parameterDbTypePropertyName" value="SqlDbType" />
    <add key="quartz.dbprovider.customProvider.parameterNamePrefix" value="@" />

    <add key="quartz.dbprovider.customProvider.bindByName" value="true" />
    <add key="quartz.dbprovider.customProvider.dbBinaryTypeName" value="Image" />

  </quartz>

</configuration>
